Leti components used in LHC experiment at CERN

Not many organizations can say they work for CERN! Well, Leti can! On November 10, 2014, the beam at CERN’s Large Hadron Collider was equipped with silicon microcoolers made in Leti cleanrooms. The microcoolers disperse heat from detectors bombarded by particles.

The project was not without some serious technical challenges, like carving out 200-micron-deep pools in the silicon. But Leti rose to the occasion, showing CERN what its researchers are capable of—just as it did in 2013 when it supplied the Geneva institute with high-pressure-resistant silicon components.

The next step will be to make around 30 microcoolers by mid-April. The microcoolers will help keep the LHC and its experiments going until 2025.
